IMPROVEMENT IAN TIME-LOCKS.

Specification forming part of Letters Patent No. 198,721, dated December 25, 1877; application filed November 13, 1877.

To all whom it may concern: Y Be it known that I, EDWARD J. WooLLEY, of Pamrapo, in the county of Hudson and vrState, of New Jersey, have invented a new and useful Improvement in Time-Locks; and I `do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and

operated by said lock, and engaging with the- Aspindle of the handle or knob of the door; also, in combining with the fluid time-lock A and intermediate mechanism operated by said lock, and engaging with the spindle, a combination-lock, engaging with the bolt mechanism of the door; also, in a contrivance for preventing the bolts frombeing withdrawn by gravity when the safe is not in a horizontal position; also,

V,in the various operative combinations of the several operative parts, all as more particularly explained hereinafter.

In order that those skilled in the art may' Y know how to make and use my device, I proceed to describe the same particularly, having Areference to the accompanying drawings, in .which- ,Figure 1 is an elevation of the inside ofa safe or vault door, showing the position of the various operative parts when the safe is un locked; and Fig. 2 is a similar elevation with dthe bolt mechanism removed, but its proper position shown in dotted lines, all the operative parts in the the safe is locked.

Similar lettersdenote corresponding parts in each iigure.

A represents the inside of a safe or vault door of ordinary construction; B B', upper and lower bolts; C, the front carrying-bar, and

position they assume when C the back carrying-bar,

for the bolts, all as usually arranged.

The iiuid time-lock D is secured, in any con- A pivoted lever-catch, E, placed between the.

bolt mechanism and the inside of the door, conveniently composed of a cross head-piece, I), the front end b1 of which is pivoted to the inside of the door, and the back end b2 is properly weighted, has a dependent arm, c, with a projection, d, upon one side, to engage with the proper cell a of the iiuid time-lock, and another projection, d', to engage with a recess, e, on the Wheel E of the spindle. This spindle, of usual construction, connected, in the ordinary way, with the knob or handle upon the outside of the door, and having a-wheel of usual form between the inside of the door and the bolting mechanism, is so placed in the ordinary position for convenient use in openingthe door, or in operating the bolt mechanism. Care, however, must be taken to so place the iiuid time-lock and the pivoted lever-catch that the latter may present its projection` d to the vcells in the iiuid time-lock when its projection d is disengaged from the recess in the spindlewheel and presses against the periphery of the same, and, vice versa, presents its projection d to the recess in the spindle-wheel while the opposite projection dis disengaged from the cell in the iiuid time-lock and presses against the periphery of the same. This spindle-wheel F has va pin, f, which projects into the opening g in the carrying-bar O, so l that by turning the spindle the bolt mechanism can be moved back and forth. G represents a combinationlock of any convenient construction, preferably secured tothe inside of the door, and behind the lower bolt B', and having its proper bolt l7s arranged so that it may engage with a suitable stop, h, on the bolt B', so as to prevent said last-named bolt from being withdrawn. A pendentlatch, H, is pivoted to the inside of the door, behind the bolt mechanism, having a rectangular slot, t', on its front edge of a size to admit a pin, g, which is secured to theinside of the bolt B, the office of which latch is to vprevent the bolts `from falling back tipped over. While the safe is in a horizontal position, the pin g readily enters into the slot c', When the bolt B is Withdrawn; but should the safe be tipped up' or turned over,thepend' ent latch Will hang vertically from its pivot,

and the slot 'i Will no longer be in line Withf the path of the pin g,and consequently this? pin Will engage with the edge of the catch either above or belowr the slot.

'Itisito be understood that, in case its'hould'f be so desired, the combination-lock maya-3e' omitted Without affecting the Working of the other parts of my device; and it is also to be observed that While the luid-lock and thelever-catch E are represented'as being'placed v'upon'the door, the 'same may be placedupon "theinside' of the safe or vault at onel side of the door 5 or the positions of the fluid time-lock and theV combination-lock may be changed rel- K atively.

`The mode of operation of my device is as Afollows, vimsuppose lvth'efsafe unlocked and :the door open, and all the parts in position, as shovvn in Fig. 1, and thei'luid'time-lockready `for operation. The door-then being closed,'by turning' thespindle to the left, the pin f crosses the opening g and presses against lthe'oppo` site-side of it, and moves thebolt mechanislml throwing the ends of the bolts `into their Vproper recesses behind the j ambs inthefsafe or vault. =By`thisfrevolution of the spindle,Y the recess 'e ofthe spindle-Wheelwhich Was-below the projection don the'lever-catch passes labove said projection about as farasbefore it' 4 lWas below it, the projection -fd on theil'ever-` f catchE at the same time f passing freely into and outy of vvthecell a in the iiuid time-lock.

Then, by turning the spindle to the right luntil the pin f-passes a portion'of the opening g, the

-projection on the levercateh drops into the recess d on the spindle-wheel, impelled thereto by the Weighted armAl b2, and attheV sametme 'the revolution of the fluid time-lock brings its cell a out of engagement With the projection d -of thev levercatch,'vvhi`ch projection then presses against the periphery ofthe fluid time` lock' until the `predetermined hour when Vthe revolution of said iuidv time -lock shallA bring a-proper i cell L vopposite the projection d. At

this point the spindle has been locked-'andypreventedl from revolution in veither 'direction by' the handle; but -the boltsa're not locked,v

vand remainv in position by inertia. Sofar as the fluid timeslock is operative, theI boltswould ydrop back by lgravity'outof f' en-l gagement With the jambs of the safe if theisame `lshould. be tipped up sufficiently. Tofpreventi this dropping back of the boltmechanism by tippingVV the safe, the; pendent' leverH-is 'oper-g ated as before explainedv 4'Vihenf theV combination-lockis r`used in con-i nection `with theV -luidl time-lock,"`the bolt'E k eti the combination-lock G, resting againstg thef those skilled' inthe business.

stopl h, preventsthe bolt mechanism from be ing-Withdrawn; but it is essentiall in all instances for better security in case the combination-lock for any reason may have beenv overlooked, or the cashier may have been compelled by force to imlock it, or in .case the -combination-lockfhas been destroyed by force,

to have the pendent lever a part of my devlce. i v

`When fthe ytime has elapsed for the predetermined revolution of the fluid time-lock, one of its cells has reached a point opposite the f'projection on the lever-catch. Then, by turn- 'ing the spindle to the right, the projectiond can enter the cell of the time-lock, and the pin f, striking against the left-handside of the opening g, will movethebolt#irame,provided the combination lock has *been already unlocked.

-The mode of setting the iliuid.l time-lockibeing described in my formeriLettersPatent,to which reference has been made, no further description of the same is deemedfnecessary.

-The advantages of my device may be briefly stated as'follows: The device is very cheap,

1The advantage of locking `the spindle f by the fluidtimello'ck, instead of locking thebolt I mechanism, isasfollows: No forcefstrain, or lpressure is -brought against the mechanism Yeither ofthe time lockl or combination lock, which force, strain, or pressure' is calculated ito 'destroyl such locks,and enable they burglar to open ithesafe `by turning the door-spindle.

In my device the strain comes primarily, and `'almost entirely,` upon lthe lever catch,

YWhich maybe made of any size and-strength, vvhile'the ordinary cembinationandA time locks are made of manypieces, and of delicate pro- =portions,fsome, ofjWhich pieces are liable to break under great pressure, or under repeated fshocks' by the spindle.

Theladvantage of usi-nga combination-lock together with the iiuid time-lock is'the convenience of locking v the safe during `tempo- 'frary absence in the day-time ;-also,f as the iiuid time-lock ceases to operate :at 'the predeter- :mined Ahour for opening the safe,thel combi- 5'nation-lock gives radditional security mshould "thecashierffor-any reason, be a little late.

AOther advantages arising from 1 my combinations will readily suggest @themselves to Having thus described my inventionand its mode ofoperation, and enumerated :some of fits'fadvantages, WhatI claim las newY therein, v-and desire to 'secure by LettersPatent, is
